Superconductors are the holy grail of energy efficiency. These mind-boggling materials allow electric current to flow freely without resistance. But that generally only happens at temperatures within a few degrees of absolute ...

(Phys.org) —To engineers, it's a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania found that for ...

A German-French research team has constructed a new model that explains how the so-called pseudogap state forms in high-temperature superconductors. The calculations predict two coexisting electron orders. Below a certain ...

Superconductors made of copper-oxide ceramics called cuprates are capable of conducting electricity without resistance at record-high temperatures—but still only at about one-third of room temperature. They also require ...

(Phys.org)—A team led by SLAC and Stanford scientists has made an important discovery toward understanding how a large group of complex copper oxide materials lose their electrical resistance at remarkably high temperatures.

Superconductivity describes the state of certain materials when they conduct electric currents without any resistance. For superconductivity to develop, these materials generally have to be cooled to temperatures below roughly ...

A Rice University-led team of physicists at seven U.S. universities has won $5 million from the Department of Defense to build a simulator capable of tackling high-temperature superconductivity, one of the most vexing mysteries ...

The coexistence of two opposing phenomena might be the secret to understanding the enduring mystery in physics of how materials heralded as the future of powering our homes and communities actually work, according to Princeton ...
